Central to Northern Coast

and Haida Gwaii (Queen Charlotte Islands) 

British Columbia

Site Description:

Our central to northern Coast region covers mainland BC and the nearshore islands from the Queen Charlotte Strait to the northern border of BC.  Much of this very large region is largely inaccessible except by boat.  Surveys have been done at many sites, but each provides only a small sample of the mollusks for the area, depending on what the survey was targeting.  
The distribution of species seems to be fairly uniform through this area so we group them all together to give a more accurate picture of  the northern half of BC.  
Haida Gwaii, formerly the Queen Charlotte Islands, lies off the west coast of British Columbia between Vancouver Island and Southeast Alaska.  
Our data encompasses both intertidal and subtidal habitat and all substrates through this region and most of the data was acquired from the collections at the Royal British Columbia Museum in Victoria, BC.

Species List:

     Following is a list of mollusk species observed at this location by members and associates of the club.  This is by no means a complete list of the species which may occur at this site.  Revisions and additions to the data are made as we acquire new information.   When a site contains more than one very distinctive type of habitat or if multiple sites were included in a single location, then a species list for each is included.
    We indicate frequency of occurrence based on our observations.  This is an indicator of how likely it is that you may be able to find this species yourself and is not a formal population survey.  

     Frequency Code:  (Based on the assumption that you are looking in the appropriate location where the species
                                          likes to live - on rocks, in sand, etc.  Some populations fluctuate seasonally.  Ours are based
                                          on the spring/summer seasons.)
     [4] - Rare - very difficult to find, maybe only a couple found after repeated visits to the site
     [3] - Uncommon - difficult to find, may not see on every trip but dedicated searching may turn up a few
     [2] - Common - easy to find, should locate a number of them on any given day
     [1] - Abundant - very easy to find, large numbers should be seen on every trip

Data is a mix of intertidal and subtidal.
Due to the nature of the data, this list will not be rated for frequency of occurrence.
